Abstract

A number of scanning devices are shown which are suitable for use in active or passive bar code readers. These devices use a mirror system which is arranged to oscillate for production of a scanning beam, the oscillation being at a resonant frequency and being effected and adjusted by means solely of magnetic or electro magnetic components.
